COURT-MARKER.

SPECIFICATION forming-part of Letters Patent No. 592,046, dated October 19, 1897.

Application filed February 27, 1897. Serial No- 625,308. (No model.)

To all whom it may concern.-

Be it known that I, GERARD G. BEEKMAN, of Hempstead, Queens county, New York have invented an Improved Court-Marker, of

horizontal section on line 2 2, Fig. 1; Fig. 3

7 a cross-section on line 3 3, Fig. 1.

and 5 are details of two of the slides g g.

The letter a represents a box having a slotted bottom a and mounted upon the shafts b of a carriage, such as a wheelbarrow. WVithin the box a there is contained a sieve 0, adapted V to reciprocate within box a and to discharge its contents through its straining-bottom c and through the slotted bottom a into a delivery-hopper d, that is arranged below the sieve and projects downwardly from shafts b.

Reciprocating motion is imparted to the sieve c by means of the traction-wheel 6 to the axle e of which there is keyed a gearwheel 6 at either side of the traction-wheel. The Wheels e intergear with wheels 6 hung in shafts b and connected by Wrist-pins e to draw-bars f. The hook-shaped rear ends f of these draw-bars are adapted to engage pins 0 projecting laterally from sieve c and passing outwardly through elongated slots a of If the hooks f are coupled to the pins 0 the sieve will be reciprocated by the revolution of the traction-wheel, while, when the hooks are uncoupled from the pins, the barrow may be wheeled over the ground without imparting motion to the sieve. In this way the discharge of the marking-powder through the sieve is at all times under the full control of the operator.

The delivery-hopper d has a dischargeopening d, controlled by a sliding gate d Figs. 4'

which moves in guide-grooves C1 and is adapted to be manipulated by a hand-chain 61 Between the rear side of the hopper and the gate d there is formed a narrow pocket.

powder and is coupled to the driving-axle,

while the gate d is opened and the proper slide is introduced. wheeled over the ground, a fine powder-line of predetermined width will be deposited upon the ground along the path of the barrow.

What I claim is A suitable frame, provided with handles at one end, and supported at the other by a traction-wheel, the traction-wheel secured to the axle, journaled in the forward end of the frame, toothed wheels secured to the shaft upon which the traction-wheel is secured, and the pinions mounted upon short shafts upon opposite sides of the frame and gearing with the toothed wheels, combined with the connecting-rods which extend through slots in the sides of the inclosing casing, the casing placed upon the top of the frame and inclosing the sieve, a reciprocating sieve, operated by the connecting-rods, and provided with pins to which the rear ends of the rods are fastened, and which pins project through slots in the lower edge of the inclosing frame, a discharge-hopper, placed below the sieve, a gate for closing the opening in the bottom of the hopper, and a series of interchangeable slides having slots of different widths, and adapted to be received within the pocket of the hopper, substantially as specified.
